PCIe AER: use pci_pcie_cap()
Use pcie_cap() instead of pci_find_capability() to get PCIe capability offset in PCIe AER driver. This avoids unnecessary search in PCI configuration space. Signed-off-by: Kenji Kaneshige <kaneshige.kenji@jp.fujitsu.com> Signed-off-by: Jesse Barnes <jbarnes@virtuousgeek.org>
